چکیده انگلیسی
Using standard methods, we describe two new Drepanomonas taxa: Drepanomonas hymenofera (Horváth 1956) nov. comb., which is composed of two (biogeographical?) subspecies, viz., D. hymenofera venezuelensis nov. subspec. and D. hymenofera hymenofera (Horváth 1956), was discovered in soil from Venezuela and Iceland, respectively. Both are comparatively large-sized (50 Ã 20 μm and 40 Ã 18 μm in vivo), differing in the cortex pattern and the structure of kineties 3 and 4. We agree with Corliss (1979) and Chardez (1990) that the genus Pseudocristigera, which was established by Horváth (1956) for Drepanomonas hymenofera, is a junior synonym of Drepanomonas. Drepanomonas vasta nov. spec., which was discovered in the mud of a tree hole in Austria, is a middle-sized species (35 Ã 18 μm) with thick body, wide left side ridges, a single anterior dikinetid in kinety 4, and an average of 99 basal bodies; it is unique in having the dorsal side much more flattened than the ventral side, thus being cuneate in transverse view. Ontogenetic data show that the ciliary pattern of Drepanomonas is homologous to that of Leptopharynx, specifically, the structure and origin of the postoral complex. Main features for distinguishing Drepanomonas species are discussed.
